REVOLVING- SHELF.

Specification of Letters Patent.

Patented Oct. 16, 1917.

Application filed February 4, 1914. Serial No. 816,401.

To all whom it may concern:

Be it known that 1, Roy CALHOUN, a

citizen of the United States, residing at Tylertown, in the county ofPikeand State of Mississippi,.have invented new and useful Improvementsin Revolvin Shelves, of which the following is a spec'- cation.

The invention relates to revolving shelves, and more particularly to theclass of dis- The primary 0b]6Ct of the invention is the provision of arack or casing wherein p the shelves are movable and driven in anysuitable manner so that the articles supported on the said shelves canbe brought in convenient reach of a person for the removal thereof fromthe same. v

Another object of the invention is the provision of a displaycasewherein any particular shelf can be stopped in its travel at thedesired point for free accessibility thereto,- the stop mechanism beingof a novel form so that the revolving shelves will be stopped toposition any particular shelf thereof in a' position to permit theconvenient removal of an article or articles therefrom.

A still further object of the invention is the provision of a case ofthis character which is practical in construction, attractive inappearance, and in which the articles or goods supported on the shelvesthereof can be continuously displayed, and also by the particulararrangement a greater economy of space is obtained, as well asconvenient access to the articles or goods supported by the shelveswithin the case. I A still further object of the inventionis theprovision of a show case wherein the shelf structure is of novel form,possessing simplicity of construction, assuring efficiency in operation,and also which is inexpensive in manufacture.

.With these and other objects in view, the invention consists in theconstruction,

combination and arrangement of parts as i will be hereinafter fullydescribed, illustrated in the accompanying drawing, and ointed out inthe claim hereunto appended.

In the drawings Figure 1 is a front elevation of a show case constructedin accordance with the invention.

Fig. 2 is a vertical transverse sectional view thereof. I.

near the top Fig. 3 is a horiz ontal sectional view on the line 3-3 ofFig. 2.

Fig. 4 is a perspective view of the adjustable stop mechanism.

Fig. 5 is a perspective view of the adjustable arm of the stopmechanism.

Similar reference characters indicate corresponding parts throughout theseveral views in'the drawings.

Referring to the drawings in detail, A designates a suitable case orhousing of any desirable shape, and is preferably provided with atransparent glass front including a drop door B adapted to be supportedin horizontal position by means of the sliding braces C of any ordinarywellknown construction, so that the door can serve as a rest for thearticlesremoved from the case.- On the opening of the door B access isreadily had to the interior of the case for removing goods or articlesfrom the revolving shelf mechanism presently described.

Mounted in the lower portion or on the bottom of the case A is anelectric motor 10, the drive shaft 11 of which has worm gear connectionwith a further shaft 13 journaled in bearings 14 suitably mounted onopposite sides of the case A, the shaft 13 being horizontally disposed adistance above the motor, and carries spaced sprocket wheels 15 overwhich are trained the sprocket chains 16 for supporting the shelvespresently described.

The sprocket chains 16 are of the endless type, and are also trainedover sprocket wheels 17 fixed to stud spindles 18 arranged of the caseand disposed horizontally in bearings 19 fixed to the sides of the saidcasing, so that on rotating-the 'shaft 13 motion will be imparted to thevarious carriers orshelves supported by the sprocket chains 16, the saidcarriers or shelves being hereinafter more fully described.

The carriers or shelves are of a similar construction, and eachcomprises a base section20 and ends 21 formed with stud sleeves 22projecting outwardly therefrom for suspending the carriers or shelvesbetween the chains 16 from studs 23 which are passed through the sleeves22 and are mounted in the links of the chain 16 at redeterminedintervals thereof. These earners or shelves will at all times assume aposition to hold travel of the chain 16 the be brought tofthe front ofarticles or goods as they are suspended and will: ravitate to suchposition during the travel of the chain so that the bases 20 will besustained horizontal. Theearriers are at will. Suitably journaled in thesides of the case A; is a horizontally disposed rock ing shaft orbar 25,the major portion of' which is of-rcctangular shape in cross section toform iiat faces 26, the shaft or bar being disposed contiguous to the.doorway in the front of the case A for free 210-" cessibilityyand on theoutermost flat face thereof is arranged suitable indicia 27 such 25" 3bi-e ng'fthe rectangular-shaped portion of a's llett ers or numerals,while slidably emsh'aftor bar 25 is a rectangular collar or sleeveportion 528 of a strikmg finger orarm 29; the latter being projectedrearwardly for engagement with any one of a series of projections30-arranged singly on the respective bases 20 of the shelves to protrudebe yond I the front edge. thereof, the projections 30 being. arranged instaggered relation to each otherto aline with the indicia 29 on r thebar or shaft 25. That is to say, each projection 30 ai lines with one ofthe characr ters 27 on the bar or shaft 25 so that the particularcharacter will designate 'one of the shelves or carriers, thus enablingthe collar or sleeve 28 to be adjusted on theshaft or bar25 in aposition whereby the arm or finger 29 will be disposed 1n the path ofthe projection 30 for contact therewith, and thus rock the shaft or rod25 which has fixed thereto near one end a trip lever 31, the trip pingnib 32 of which is projected into the i path of the arm 24 of the switchso that the latter will be automatically tl'irown to out off position onthe rocking of the shaft for the stopping of motor; thereby/bringing thedesired can-lento a sta;ndstilldirectly in front of the door 13 so'thataccess may be had thereto for the removal of its contents.

The collar or sleeve 28 at the front thereof is formed with a peepopening 33, which oni ables the reading of the characters ontheSaid'ha'ndle enables the 10f the collar to adjusted Connected to thetrip end is one end of a coiled retractile spring or sleeve '28 directlyover any of the charactors, the collar havingformed upon one sidethereof a hand hold 34 arranged between the. arm 29 and peep opening 33.convenient sliding position. v a

1ever31 at its free 35 which has its opposite end connected to the sideof the case Aland is adapted to exert a pull upon the trip lever 31 tonor mally hold it against a stop 36 fixed to the side of the casing A,and thereby hold the rod or bar against rocking movement so that thefinger or arm 39 will be projected to engage one of the series ofprojections 30 on the shelves. It is to be understood, however, thatnormally the arm or finger 29 is positioned at any point between thepathof movement of the projections 30 so as not. to interfere with therotation of the carriers when the motor 10 is operated, so that thearticles or goods in the carriers will be brought to'view by thesuccessive travel of the carriers to the front of the case.

On the arm 24 of the switch is a handle 37 which enables the manualmanipulation of the arm for the opening and closing of the circuit,thereby enabling the motor to be stopped or started at will.

From the foregoing it is thought thatthe construction and manner ofoperation of the device will be clearly understood, and therefore a moreextended explanation has been omitted.

What is claimedis:-

In a device of the class described, a casing having an opening extendingtransversely of the front thereof, a stop inex nber on said casingadjacent an end ot said opening, movable supports within said casing,means for moving said supports, controlling mechanism for said meansincluding a rock shaft within said casing contiguous to said opening andoperable by said movable supports, a switch in said casing above saidstop mom,- her, and a trip arm on said rock shaft to engage, said switchnormally held in contact with said stop member. it

In testimony whereof I ailix my signature in presence of two, witnesses.
